About the rev limiter:

It doesn't cut off spark, actually. If it did that, you'd be pushing a
*huge* charge of fuel-air mixture into the exhaust; much more than the
catalytic converter could handle. Picture the results when the revs
dropped below 7 grand.  no exhaust system. :-(

What the rev limiter actually cuts off is the fuel injection. Spark with no
fuel is fine. Useless, but fine. :-)
